Enrique Ramiro Pujals is an Argentine-Brazilian mathematician known for his contributions to the understanding of dynamical systems.
Education
After earning an undergraduate degree in mathematics at the University of Buenos Aires in 1992, he became a Ph.D. student at the Instituto Nacional de Matemática Pura e Aplicada, where he was a student of
Jacob Palis, completing his Ph.D. in 1996.
He was a Guggenheim Fellow in 2000.
Before moving to CUNY in 2018, he was a faculty member at IMPA since 2003.
Awards

Beijing 2002.
Won the ICTP Ramanujan Prize (2008), UMALCA Prize in Mathematics (2004),
(2009), is a member of the Brazilian Academy of Sciences
and receive the Brazilian National Order of Scientific Merit in 2013
